HP Compaq Presario CQ56-151SR DA0AX2MB6E0 REV E

BIOS .rar 1.18 MB Shared

BIOS firmware package for the HP Compaq Presario CQ56-151SR laptop, built around the Quanta motherboard DA0AX2MB6E0 at revision E. The RAR archive is about 1.18 MB and should contain the SPI flash image for this board. The DA0...MB... numbering pattern belongs to Quanta, the ODM that made the board for HP. Before writing it with a programmer such as a CH341A, confirm the board number and revision printed on the PCB, save a backup of the original chip, and check the image size matches the flash capacity.
